Method and system for reducing reporting of non-malicious electronic messages in a cybersecurity system

A client electronic device of an electronic message analysis system receives a user activation action indicating that a user has reported a message received at the client device a potentially malicious. The client device then determines whether to forward the message to a remote service for analysis by assessing whether the received message originated from a trusted sender. If and only if the client device determines that the received message originated from a trusted sender, it will permit the client device to take other action on the received message and not report the received message to a remote service for further analysis. If the client device does not determine that the received message originated from a trusted sender, it will report the received message to a remote service for further analysis.
